Jan 01, 2000· An electrowinning unit has three main components: 1) electrolytic cell; 2) rectifier; and 3) pump. An electrolytic cell is a tank in which cathodes and anodes are typically arranged in alternating order (Fig. 1). The cathodes and anodes are attached to their respective bus bars, which supply electrical potential to the unit.
Generally used with gold and silverbearing cyanide solutions, our cells have also been used successfully with noncyanide metalbearing solutions. We offer cell sizes from 50 to 150ft of cathode equivalent volume, normally ranging from 500 to 2000 applied amps per cell, as shown in .
The remaining copper you can mantein in solution during electrowinning stage with low parameters of current and voltage in electrowinning cells. To obtain better results you must increase cyanide concentration and pH. I worked with 4000 ppm cyanide and 14 pH. I advise try in laboratory at first. Sorry for my poor english regards
A cylindrical electrowinning cell employing a threedimensional steel wool cathode has been used to investigate the effect of free cyanide concentration, pH, solution conductivity and base metal impurities on the electrowinning of gold from alkaline cyanide leach liquors containing up to 5 mg/l gold.
The objective of this work is to study the effect on copper electrowinning of the cyanide/copper molar ratio, the potential applied to the electrolytic cell, the temperature and circulation rate of the solution, and the use of synthetic solutions with physicochemical characteristics similar .
To a great extent, the calculations made to size a standard gold electrowinning cells are based on data and models reported by Roger Paul of Mintek in SA. Extensive plant data collected and interpreted by Mike Costello (Australia) has been used to further enhance the methodology used to size common gold EW cells. Discussion presented is based ...
What distinguishes the lonnet most from other electrowinning systems is the expanded surface area cathodes and the unique solution flow design.. It has been reported to us that 60% – 80% of the free cyanide in a 500 gallon solution was destroyed in 48 hours of operation at 400 amps.
